PORTABLE CONVEYER.

To all arr/1.0m.- 1' may concern.

Be it known that I, Print? L. \Voosrnn, a citizen ,of the United States, residing at Yonkers, in the State of New York, have invented certain new and useful Improvements in Portable Conveyers, of which the following is a specification.

This invention relates to that class of portable conveyers adapted to be used upon docks and wharves for the purpose of loading and unloading vessels, or for similar purposes, the device comprising a framework mounted uponwheels so that it can be pushed around and adapted when in use to rest at its opposite ends upon the two surfaces between which the freight is to be carried, the said framework supporting an endless conveyer belt and means for driving the same which is self-contained inthe device, such as an electric motor.

The objects of the invention are to secure a simple construction the parts ofwhich are not liable to get out of order; to provide ready access to the diiierent parts of the device, and enable the motor to be removed if desired; to secure a strong construction which will not be racked or loosened by usage; to prevent any lodgment in the device of dirt or other droppings from the stock material can be largely material being conveyed; to avoid a multiplicity of parts by making portions of the frame serve also as guideways for the convey'er belt; to secure a constructionin which used, and to obtain other advantages and results as may be brought-out in the following description.

Referring to the accompanying drawings, in which like numerals of reference indicate the same parts in the several figures, Figure I is a side elevation of a portable conveyer of my improved construction in position for use; Fig. 2 is a side elevation, on larger scale, of that end of the eonveyer where the conveyor belt can be adjusted; Fig. 3 is a lan of the conveyer; Fig. 4; is ,a section taken longitudinally of one of the conveyer belt slats and transversely of the supporting rail for said belt,'as on line et-4:,Fig. 6, illustrating a. certain friction shoe; Fi 5 is a section transversely of the conveyer belt slat, as on line 5-.5, Fig. 6; Fv

Application. filed September 16, 1908. Serial No. 453,257.

Fig. '7 is a transverse section of the conveyor taken on line 7-7, Fig. 8, looking in the directionindicated by the arrow; Fig. 8 is a side elevation of the middle portion of the conveyor, the adjacent wheeland a portion of the adjacentframework being broken away to show the construction more clearly; 9 is a vertical section of that end of the conveyer at which the conveyer belt is driven, said section being taken longitudinally of the conveyor, as upon line 9-9, Fig. 10; Fig. 10 shows in plan the opposite ends of the conveyer, the middle portion being broken away and the conveyer belt removed for=greater clearness; Fig. 11 is a detail view looking at the ends of the conveyor belt slats, of another means for supporting the conveyer belt; Fig. 12 is a view of the same looking at the lateral edge of one of the con as shown, and beneath saidupper bars 10, lower bars 11, 11 also of angle iron. These lower bars 11 are each inclined at their ends toward the upper bars 10 lying in the same vertical plane, while the middles are farther away from said upper bars, as shown in Fig; 1. so as-to give a Beneath the said lower bars 11, 11 and parallel thereto, are other bars 12, 12 of T-iro'n, each arranged oned'ge with its stem portion projecting horizontally inward. Each of the said angle irons 10 and 11 is also arranged with one of its iiangesprojecting vertically upward-and the other as shown. Each upper bar 10 of the frame is connected with the lower bars 11 and 12 by means of transverse struts 13 and intruss form to the frame.

horizontally inward,

said bars, said struts and braces being profs erably also of angle iron, 7 braces and struts, 14 and 13- may be riveted preferably some of them.

If desired, these 10, 11 and 12, butv and es ecially; those at the middle of the length of t e coir.

veyer, are removablybolted in place, so as to permit of their removal to obtain access to certain parts of the mechanism hereinafter descrlbed. The two side portions of the frame are held in relative 'parallel positions by means of angle bars ne'athv the upper bars 10 'in the corners 'formedwith the transverse struts 13, and by 4 ends, as shown at 18 in Fig. 9, while the upper angle bars 10 are also shorter and straight. atthei'r ends like the lower ones 11.

Plates 20 (or 21) are then laid fiatwise against the outer sides-of said ends of the bars and riveted. bolted, or otherwise secured thereto. Tie rods 22 mayalso connect thevtwo opposite end plates, with tubular separators thereon between said plates (see Fig. 9). A very strong and rigid frame is thus provided and beneath said frame at its middle is arranged an axle 23 with wheels 24'thereon which enable the conveyer to be conveniently moved from, place to place. The said axle 23 is ournaled in brackets 25, 25. suitably bolted or riveted to the bottom Tbars 12 of the frame, as shown in Figs. 7 and 8.

Between the end plates 21, 21 at one end of the frame extends a transverse shaft 26, journaled at its ends in bearings 27 upon the said end plates. This shaft has fast upon itself a middle bevel gear 28 and sprocket wheels 29, 29 near itsopposite ends. The end plates 20, 20 at the other end of the frame have slideways 30 formed therein and in which slideways are mounted boxes 31 adapted to be moved back and forth longitudinally of the frame by means of a screw 32 and nut 33 therefor, asis common. The said two boxes 31, 31 afford journal bearings for therends of a transverse shaft 34,.

which shaft has near its ends sprocketwheels 35, 35 in alinement with those 29, 29

just above described at the other end of the frame. These two sets of sprocket-wheels receive the endless conveyer belt 36 which will next be described. This conveyer belt *comprises a series of transverse slats 37 each secured near its opposite ends to chains 38, 38, adapted to run upon and be driven by the said sprocket-wheels 29 and 35. These slats 37 lie at the upper part of the frame betweenthe upwardly projecting flanges of the upper angle bars 10, 10, as shown in f Fig. 7, and thus the beltjis held positively against sidewise displacement. 'llo support the said conveyer belt for the upper carbon .of the frame, and the weightcarried y said:

15, secured be-v and 7.the said slats each belt, rails 39, 39 are arranged upon the angle bars 15, as shown in Figs. 7 and 10 more especially and upon which the transverse slats 37 slide. In order to prevent undue friction and wear of the slats 37 upon the said rails 39, I have shown in Figs. 4, 5, 6

provided at the opposite edges of itsunder surface which engages a rail, with recesses 40, in which are run blocks 41 of Babbitt metal or the like to 'take the friction. These said recesses 40 have undercut walls and the block 41 has a stem projecting into a socket 421 of the slat, whereby the blocks or shoes 41 are securely retained in place. The said blocks or shoes project from the surface of the slat, as shown, so as to entirely relieve the latter of any friction. Furthermore, the said blocks or shoes can be replaced by new ones when desired, without great inconvenience. In returning, or at the lower part of the conveyer, the belt 36 passes idly between the horizontal flanges of the lower angle bars 11 and the stems of the T irons 12, the slats resting near their ends upon said stems and their ends abutting against the vertical portions of the T iron as shown in Fig. 7.

For driving the conveyer belt 36, an electric motor 42 is mounted inside the frame at its middle, being set on a platform 43 formed by plates 44 laid across between the lower angle bars 11, 11. This motor drives a pinion 45 which meshes with a gear 46 on a shaft 47 journaled transversely of the frame in bearings 48 upon two of the "upright struts 13. This shaft also carries a bevel pinion 49 which meshes witha second bevel gear 50' upon a power-transmitting shaft 51 which extends longitudinally-of the frame and is mounted in bearings 52 supported by angle-iron cross-bars 53 between the side struts 13. This shaft 51 has at its opposite end a bevel pinion 54 engaging with the bevel gear 38 on the sprocket shaft. Preferably the said shaft 51 is provided intermediate of its said ends with a clutch 56. Under some conditions, the said frictionshoes 41 may be dispensed with, and the chain 57 which connects the slats and runs 'over the sprockets may be of a type having rollers 58 adapted to run upon the rails 59, all as shown in Figs. 11, 12 and 13. This chain is of any well known type, having sections 60 adapted to be s'ecured to the slats 371, said sectlons be ng connected by pivoted pins 61, upon which the rollers 58 are mounted.

I have marked with reference numeral 19 the side strut which is shown removable to permit access to the motor 42 or to remove the said motor from the conveyer frame, and 55 indicates the bolts by which it Is so removably secured. Obviously, more than one of the struts and braces could be so arranged, if desired.
